Sqrt

Sqrt  //  Elementwise square root operation

Description

Produces a tensor of the same element type and shape as arg, where the value at each coordinate of output is the square root of the value at the corresponding coordinate of arg.

Inputs

Name Element Type Shape
arg Any Any

Outputs

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \sqrt{\mathtt{arg}_{i_0, \ldots, i_{n-1}}}\]

Backprop

\[\overline{\mathtt{arg}} \leftarrow \frac{\Delta}{2\cdot \mathtt{output}}\]

C++ Interface

class Sqrt : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise square root operation.

Inputs

Public Functions

const std::string &description() const

Get the string name for the type of the node, such as Add or Multiply. The class name, must not contain spaces as it is used for codegen.

Return
A const reference to the node’s type name

Sqrt(const Output<Node> &arg)

Constructs a square operation.

Parameters
  • arg: Node that produces the input tensor.
